include: Silence external kernel version checks

During the initial configuration phases, we have not set-up the kernel source directory, which would lead to such messages: cat: /local/users/fainelli/openwrt/trunk/build_dir/target-x86_64_musl/linux-uml/linux-4.9.58/include/config/kernel.release: No such file or directory Just silence it, since it does not create a functional problem. Fixes: 8e0e0e7 ("include: Determine MODULES_DIR correctly for external/git kernels") Signed-off-by: Florian Fainelli <[email protected]>
